Translations:Routing penalties/Controlling U-turn penalties/4/en
- Three segments: The U-turn is a reversal of driving direction through three segments:
an incoming segment (A), a single median segment (B) and an outgoing segment (C).
- Short median: The median segment (B) is shorter than 15 meters (49.21 feet).
As a safety margin, leave a 1 m buffer zone by using 14 meters (45.93 feet) or less.
- In/out parallelism: The in and out segments (A and C) are within ±5° of parallel to each other.
|It is possible for this method to fail to prevent a U-turn when it is the first segment of a route, or it immediately follows a reroute. If you observe this method to fail in other situations when it is implemented properly, please report it in this forum thread|
